Embodiment Construction
[0024] The present disclosure is best understood by reference to the detailed drawings and descriptions set forth herein.
[0025] figure 1 The structural diagram of the wireless watch provided in this embodiment, the wireless watch includes the following four parts:
[0026] The first part is the ARM processor. The resources used by the ARM processor include SPI interface, serial port and GPIO to simulate I2C IO resources;
[0027] The second part is the HT7038 electric energy metering chip. One HT7038 can measure single-channel three-phase electric energy at the same time, and the price is low. It uses the SPI interface for data acquisition;
[0028] The third part is the data storage module, which is used for power-down storage, which uses the I2C interface for management;
[0029] The fourth part is a zigbee communication module, which is used for data interaction with the host computer. The zigbee communication module uses the global 2.4g free frequency band, which has ...

The invention provides a wireless ammeter. The wireless ammeter comprises an electric energy metering chip, a data storage module, a wireless communication module, and a processor; the electric energymetering chip is capable of simultaneously measuring single-path three-phase electric energy; the data storage module is used for saving electric energy during power outage; the wireless communication module is in wireless communication connection with a power and environment monitoring system; and the processor is used for obtaining the metering data of the electric energy metering chip, storingthe metering data in the data storage module, and sending the metering data to the power and environment monitoring system through the wireless communication module. The invention also provides a usemethod for the wireless ammeter. The electric energy metering chip measures the single-path three-phase electric energy, and sends the single-path three-phase electric energy to the processor; the single-path three-phase electric energy is stored in the data storage module, and is sent to the power and environmental monitoring system through the wireless communication module. According to the wireless ammeter and the use method thereof of the invention, a wired ammeter in a traditional power and environment monitoring system is updated to a wireless ammeter, and therefore, the deployment costof the whole system is decreased; and additional manual wiring is not required, various fault points caused by lines can be reduced, and the security of the whole system can be improved.
Description
technical field [0001] The invention mainly relates to an electric meter, in particular to a wireless meter used in a power and environment monitoring system. Background technique [0002] In the power and environment monitoring system FSU, it is usually necessary to configure an electric meter to measure the electricity usage of the site. Conventional power and environment monitoring systems use serial ports or network ports to aggregate data into the FSU host for unified management, so the supporting electric meters also use serial ports or network ports to transmit data. The disadvantages of this form of system are: [0003] 1. The deployment cost is high, and manual wiring installation is required. [0004] 2. There are often failure points such as line aging and line damage. Contents of the invention [0005] The technical problem to be solved by the present invention is: how to reduce the deployment cost of the power and environment monitoring system for meter man...
